1 / 9 page D2706 TI IM B8-9145 No.A0082-1/9 LB11660RV Overview The LB11660RV is a single-phase bipolar half pre-driver that can achieve high-efficient direct PWM drive with ease. It is ideal for driving small-sized cooling fans used in servers. The LB11660RV is provided with the RD (lock detection) output pin and the LB11660FV the FG (rotational speed detection) output pin, respectively. Features • Single-phase full-wave drive (15V-1.5A output transistor built in) upper output Tr incorporated half pre-driver. • Variable speed control by an external signal. →Separately-excited upper TR direct PWM control method, enabling silent, low-vibration variable speed control. • Lowest speed setting possible. • Current limiter circuit (the circuit actuated at IO = 1A when Rf = 0.5Ω, Rf determines the limiter value.). • Kickback absorption circuit built in. • Soft switching circuit achieves low power consumption, low loss, and low noise driving at a time of phase change. • HB built in. • Lock protection and automatic reset functions incorporated (including a circuit that changes the ON/OFF ratio according to the power supply voltage). • RD (lock detection) output. • Thermal protection circuit incorporated (design guaranteed). Ordering number : ENA0082 Monolithic Digital IC Single-Phase Full-Wave Driver For Fan Motor Any and all SANYO Semiconductor products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO Semiconductor representative nearest you before using any SANYO Semiconductor products described or contained herein in such applications. SANYO Semiconductor assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor products described or contained herein. |
